Lemme clarify futher. Its easy to be a chemist in undergraduate and go on to be a good graduate or postdoc biologist. Its harder to be a biologist in undergraduate and be a good chemist later on. An example is thus: You wanna go to med school (why, I don't know..maybe its a mental problem. MDs work ...

Denaturation DOES NOT alter or sever the the primary protein structure (amino acid sequence). It does, however, alter the secondary, tertiary and quarternary structure. Digestion on the other hand, breaks a protein into the constituent amino acids. There is a difference, it is a big deal, and we nee...

Its more because the peptidoglycans are exposed on the surface of gram+ bacteria while gram- have another phospholipid bilayer over the peptidoglycans. Since the gram stain interacts with the peptidoglycans, the gram+ stain darkly while the gram- don't.

Be a chemistry major with a biology minor. For what you wanna go into, you'll be better off having a better grasp of the chemistry than blowing time having to take courses in botany or wasting brain-space on stuff like anatomy. Dr. Philip Sharp from MIT is a recent (10 or so years ago, I forget) Nob...

Administering drugs, obtain from molecular biology or any other source is teh privilege of doctors Privilige my eye. Dealing with the public off the street is a curse. Bacteria and yeast don't whine and talk back and they sure as heck aren't non-compliant with their meds. Heck with that... -Jelanen

Topic: What is the pupose of phosphorylating glucose in cytosol?
Replies: 11

The answer is 1. Glucose doesn't diffuse through cell membranes, its transported. There is a transmembrane transporter for glucose, but not for glucose-1-P. Phosphorylating glucose locks it into the cell, preventing it from escaping. Adding a phosphate does nothing to help the solubility of glucose....

Yeap... Inferiour animals... xcept for sponges the most inferior animals... Inferior? Thats a very anthropromorphic term. Maybe the jellyfish think humans are inferior since we don't have nifty microscopic neurotoxin tipped harpoon launchers. Maybe they think we're inferior cause we don't have pret...

From http://www.ruf.rice.edu/~bioslabs/studies/mitochondria/mitopoisons.html The compound 2,4-dinitrophenol (DNP) acts as a proton ionophore, that is, it binds protons on one side of a membrane, and being fat-soluble it drifts to the opposite side where it loses the protons. Actually, the associatio...

I don't know what countries grow Golden Rice. I don't know if its dangerous or not, but I think the issue has become more of an anti-biotech issue for the eco-activists than anything else. For those who don't know, Golden Rice is rice that has been genetically modified to produce prodigous amounts o...
